Dinuguan (Pork Blood Stew) or Dinardaraan in Ilocano is a Filipino dish usually made 
from the blood, entrails and meat of a pig. It is sometimes known as "chocolate meat" 
as the stew has a thick chocolate-like color and consistency. The name "dinuguan" is 
derived from the Filipino word "dugo", meaning blood. Likewise, in Ilocano, 
"dinardaraan" is derived from the from "dara", meaning blood. Dinuguan has more liquid, 
while dinardaraan is drier.

Ingredients

    * 3 cups (700g) cubed boneless pork butt with fat (½-inch cubes)
    * 3 tablespoons lard or peanut oil
    * ½ cup (120ml) vinegar mixed with 1 cup (240ml) water and 1 tablespoon salt
    * 1 medium-sized yellow onion, peeled and sliced
    * 1½ cups (360ml) pork blood (Ideally from Vietnamese, Filipino or Western European 
markets)
    * 3 cloves garlic, peeled and crushed
    * 2 hot jalapeño peppers, seeded and chopped

Procedure

   1. Place the pork in a 4-quart (560ml) covered stove-top casserole dish and add the 
vinegar mixture. Bring to a boil and reduce the heat.
   2. Cook, covered, for about an hour, until the pork is tender. Make sure that the 
liquid doesn't dry out. Add more water if necessary.
   3. Heat a frying pan and add the lard or oil.
   4. When the oil is hot enough, sauté the onion and garlic until the onion appears 
translucent. Remove from heat.
   5. Add the oil, garlic, and onion to the pork and continue cooking for 5 minutes.
   6. Purée the pork blood in a food processor.
   7. Add the blood to the pork gradually while stirring the mixture. Bring to a boil.
   8. Add the chopped pepper and simmer uncovered to reduce the sauce until desired 
thickness is achieved. Keep covered and serve hot.

This is most often served over rice or puto (sweet steamed rice muffins).
